- bein csiec-iall directed to the "overnim b r: a

and sparking mechanism therefor, and has for its objects to produce acomparatively simple, inexpensive device of this character, wherein oneof the sparking members will be moved out of the path of the otherduring each alternate instroke of the piston, or that is, during theexhausting intervals, and one wherein the movable sparker will, m theevent of the engine speed increasing beyond apredetermined limit, beautomatically moved out of the path of the other spark-er and maintainedin such position until the speed has decreased to normal.

. A further object of the invention is to provide a device of thischaracter with a sim-- plified form of mechanism for operating themovable sparker, one in which said sparker will be automaticell moved toinactive position siniultaneousltv with the opening of the exhaust port,and one wherein the parts will upon an abnormal increase in the speed ofthe engine be locked for maintaining, the exhaust open and the movablesparker in inactive position.

'With these'and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the'accompan ing drawings: Figure l is a side elevation e an en ineequipped with a mechanismembodying t e invention. Fig. 2 is a. similarview looking from the other side of the engine; Fig. 3 is a rearelevation of theisame.

, Referring to the drawings, 1 designates an engine base sustaining a.cylinder 2 in which is and ed for reciproeationa piston 3, the rod 4which is connected at its rear end with eccentrics 5 carried by a driveshaft 6 'ournuled in suitable'split hearings in the base 1 and euuinpedwith lly wheels 7, these parts except as may be hereinafter exit beingof the. usual or any preferred tinnsc i'rxe-il upon the shaft 6 forrotation there- 'lfi'!

(lit-axed b v the arrow in Fig. 4, and fora purposeEmiiCl'l will hereinafter appean In rvlinder 2 is )I0\' ltlt with aninlet l port 2 and with an exhaust port 21 adapted suitpfi able 5; atthe rear end of the cylinder and having a valve carried b v alongitudinally movadapt swung urn ard, as heretofore cxplnlncd. j

Fixed upon the outer end of shaft 37 is a .crank arm 40 to the outer endof which there is pivoted by means of a tubular coupling member 41, ahearing member or sleeve 42 having slidably arranged therein the upwardend of a rigid connecting element or red 43, the rear end of which isconnected by means of an eccentric strap 44 with an eccentric 45 fixedupon the shaft 10, there being arranged upon the rod 43, which isprovided at its up ward end with a head ore largement 46 a normallyexpanded spring $7 arranged to hear at one end against the sleeve 42 andat its other cndagainst a bearing shoulder 43 on the rod, while fixedupon theshaft 10 at the end thereof remote from thhgcccentric 45 is acam member or head 49 arranged in naled to the lever 30 and adapted folocking the latter to move the rod 29' forwhrdly as indicated by thearrow in Fig. l to operate the rock shaft26 for actuating the exhaustvalve to open the port 21.

Journaled in the-tubular coupling member 41 is a second coupling memberor pm 51 hav vrovidcd with a bearing opening 53 in which is slidablyarranged one end of a connecting rod or link 54 provided at a pointsnitabl remote from said end with a bearing shoulder 55 and having itsother or forward end pivotally of .a coupling link 56 with a fixedbearing phrtion or arm 57 projecting from the outer end of crank arm 25,as seen more clearly in Fig.

In practice, as the'shaft 6 rotates the shaft 10 will be driventherefrom through the me dium of gears 8 and 9 and the cam head49 will,during each rotation of the shaft 10, set upon the roller 50 for rockinglever 30 and moving the governor rod 29 forwardiy, wherebv the rockshaft 26 will be operated to move t 1e arm 25 into contact with and foro enin the exhaust valve as herein after exp aine it ben J understoodthat the shape of the cam 49 is such that the exhaust valve will be opendurin each alternate instrohe of the piston 3-, or that is, during aproprisze intervals for exhausting the explo ed gases from the cylinde 2.During the rotation of shaft 10 the rod 3 will be actuated throughcontact with'an antifriction roller 50 jourwar'd through the medium ofcrank arm 25 a 1 operation, as just explained. It will be seen connectedby means 'ooepn the medium of the eccentric 45 for iockingthe shaft 37to move the sparking member or contact 38 into and out of the path ofthe 00* operating sparking member 39, it being inderstood that duringthe normal operation of the parts the movement of the contact 38 toinactive position, or that is, out of the path of the sparker 39,will'be simultaneous with the exhausting stroke of the piston 3 and themovement of the exhaust valve to open position, and further that undernormal conditions the rod 54 will havesuflicient longi-. tudinal play inthe bearing opening 53 to permit the proper movement of crank arm 40without coming incontact with the stop shoulder 55. hen the speed of theengine increases beyond the normal the governor members 17. will,'inswingin outward, move the rod 11 longitudinally and throw. the lock-..ing member 12 into the path of keeper 32, as heretofore explained, thus.locking the governor rod 29 against movement with the exhaustvalve open,under which conditions the link 54 will be moved longitudinallyrearsuflicient distance to bring the abutment 55. into contact with thehead 52 andact upon the arm 40 for fixing the shaft 37 against movementwith the sparking member .38 held out of the path of sparking'member 39,in which position the parts will be maintained until speed of the enginedecreases "Suthcicntly for the governor members]? to return to normalcondition under the action springs 18, whereupon the locking member 12wi 1 be actuated or releasing the partsnnd permitting a continuance oftheir normal at when the locking rod-54 is moved to sition for holdingthe arm 40 and shaft- 37 against movement the s rin 47 ermit the rod 43to play i ly hack an forth through the bearing 42.
